25 RDS Summit TV won't scan channels.

pawpaw · 08-21-2022, 04:15 PM

Noticed it yesterday. TV has power but shows to run a scan. Runs through the channels and shows the number of RF found but no local channels. Checked all connections..plugs and shows no light on the rear box where the module for the Key TV is. Bad module or tuner inside the TV is my guess. Camper has the Winegard Air 360+ V2.s antenna. Furrion stereo is working OK and I'm guessing the antenna is working. Camper is hooked to a 50 amp pole and has a Southwire surge guard hooked to it. Still have workers re-doing the inside of my house from Hurricane Ida last year so its my hang out place sometimes. Never had a problem with scanning channels in any of our other campers.

It's more likely your KeyTV is failing than your TV is failing. KeyTV is problematic. If there is no light on the KeyTV box, that's a pretty good indication.

Got a set-top TV antenna? Hook it up. I bet your TV finds a few local stations.

As stated, if the blue light on the KeyTV module isn’t lit, your not getting 12V to it. 12VDC is sent to the antenna through the coax to amplify the signal. If you take the module out you can test the leads to verify 12V to the module.

I'll try that tomorrow...thanks for the tip!

Nope it's not lit. Looks like Key TV may be problematic. Camper is only 3 months old. Thanks for the help!

I can't really speak to your ultimate solution but I can say that with mine I had multiple issues; KeyTV would not work and had to have the module replaced. The Furrion TV would not "scan" antenna channels (or any other). They replaced and rewired the KeyTV module and cables and we replaced the Furrion with a Vizio smart tv that works.

Sounds like the identical thing going on with mine. Only difference it's a Summit TV. This is our 3rd camper and never had any problems with the old school design! At least it played great for 3 months. Thanks for the help.

Well..well..well after a severe thunderstorm rolled through this evening I went out to the backyard and checked on the camper. Ran a scan on the TV and it worked! A miracle!!!

Shocking! Simply shocking!

Still without a light on the KeyTV? Bizarre.

Miracle #2 happened when my I-phone decided to pair with Bluetooth on the Furrion receiver. Lightning storm must have helped out this evening!

Guess it was a short lived miracle. Key TV not working again..2 days it worked OK but crapped out today. Blue light not working either.

Key TV has been an issue in the past. IIRC some reports were that after it was turned on for a period of time it would overheat and shut down.

It seems to me a lot of so called improvements benefit the factories more than the customer. Electronic modules have been a PITA over the years. I had a '77 LTD that had 2 modules go bad due to heat. Even had the power pack on my Evinrude outboard overheat and shut the engine down. Must be the grandkids of the 1970 and '80 builders putting them together in todays world!

See you're in Maryland...wifes sister lived in Frederick for over 30 yrs and we made many trips up there. Hauled a lot of seafood and other things from the New Orleans area they couldn't get up there. Nice area plus we would get to see snow around our Christmas visits.

Yup, if the electronics can add some "gee whizz" effects that boost sales they'll slap it on.

Fredrick is about 50 miles west from us but it's pretty out there near the Catoctin mountains but there sure aren't any shrimp this far north.

I have the same model Cougar and my Summit TV is doing the same thing. Showing my ignorance here, but where is the Key TV module?

Bob I watched 4 videos and walk through and the only thing I saw was in the following link at the 7:44 mark. My Key TV has an actual module vs the little connectors they show there and I believe any Key TV would have to have the module to differentiate signals. It's possibly right behind that exterior connector. Since they did it that way it could however be stuck anywhere.

Open the box above the rear bumper. Remove the 4 screws and it's right behind the panel with the cable/satellite connectors. The blue light when its working is on the bottom left. Make sure the connections with cables are tight. You can also access this by removing the rear dinette cushions and thin plywood cover underneath. I tightened up everything and it worked one day. I may have to bring it into the dealer to have them check it out before they order a new module. Bought a cheap rabbit ear antenna and it works OK on the TV for local channels only. Don't think Key TV is as good as the old school version!!

It's not as good as the old school version! While touting it as an "advancement" it was simply a way to reduce costs by eliminating coax for 2 separate systems and the labor time to install them. The Key TV modules have been problematic since being introduced.
